Hi all,
I'm trying to implement a Click2Dial service by using the dlg_bridge command from the dialog module. Although it works in this case, I found two problems in the scenario and I would like to read your opinion about them.
1) Fisrt problem: the REFER generated by Kamailio doesn't contain a contact header. As per RFC 3515, this request should have a Contact header. This REFER is not being accepted by a proprietary device. This is can be worked around with the append_hf() command from the textops module, but I don know if it is a good solution.
2) The second one arises when the ACK generated by Kamailio, goes through Kamailio (caller and calle involved in click2dial are registered on the Kamailio server): the branch of the second via header is not correctly populated. Its content is '0' when it must be tha same as in the INVITE.
Below you can find the traces of the whole scenario. Could you take a look at them and give me your feedback?
Thanks in advance, best regards
Antón Román
